20080294102 | Balloon Cannulae - A vascular catheter with a circular external diameter, a circular lumen contained within, and an inflatable balloon that overlies a trough in the catheter body such that when the balloon is deflated, the balloon does not protrude beyond the outer circumference of the catheter shaft. The wall of the catheter shaft is thicker along one side than along the remainder of the circumference of the catheter shaft to permit an inflation lumen to be disposed within the thick wall section without increasing the outer diameter of the remaining portion of the circumference. The inflatable balloon is further disposed to maintain the circular lumen of the catheter in the center of flow of the blood vessel in which it is used, maintaining optimal flow. The combination of the circular lumen, circular outer diameter, and recessed balloon trough produces improved hemodynamic flow characteristics within the cannula over existing balloon cannula designs, minimizing flow-related injuries that might cause embolization or vascular dissection. | 11-27-2008 |
20090125102 | IMPLANTABLE DEVICES FOR CONTROLLING THE INTERNAL CIRCUMFERENCE OF AN ANATOMIC ORIFICE OR LUMEN - An implantable device for controlling the circumference of internal anatomic passages corrects physiologic dysfunctions resulting from a structural lumen which is either too large or too small. Implants are disclosed which employ various means for adjusting and maintaining the size of an orifice to which they are attached. Systems permit the implants to be implanted using minimally invasive procedures and permit final adjustments to the circumference of the implants after the resumption of normal flow of anatomic fluids in situ. Methods are disclosed for using the implants to treat heart valve abnormalities, gastroesophageal abnormalities, anal incontinence, and the like. | 05-14-2009 |
20090234404 | Methods and devices for modulation of heart valve function - Methods and devices for modulating heart valve function are provided. In the subject methods, a heart valve is first in structurally modified. Blood flow through the structurally modified heart valve is then monitored, and the heart is paced in response to the monitored blood flow. Also provided are devices, systems and kits that find use in practicing the subject methods. The subject methods find use in a variety of applications. | 09-17-2009 |
20110009956 | MAGNETIC DOCKING SYSTEM AND METHOD FOR THE LONG TERM ADJUSTMENT OF AN IMPLANTABLE DEVICE - An implantable device for controlling the circumference of internal anatomic passages corrects physiologic dysfunctions resulting from a structural lumen which is either too large or too small. Implants are disclosed which employ various means for adjusting and maintaining the size of an orifice to which they are attached.
